According to legend, the Caliph at Giltat made a deal with the Al Harwaz, creatures who offered trade if his people learned a dance. The Caliph had the Al Harwaz help him win the war against the Kebiriz, but had them killed afterwards. The Al Harwaz responded by using flying monsters to destroy him and his city.

It was substantially unclear whether the events of the subsequent Big Bang Two erased Amy and Rory's presence in the 13th century. This ambiguity was caused, in part, because the non-Auton, married Rory Williams claimed to have remembered being "made of plastic" at his wedding reception, suggesting that, at least inasmuch as he was concerned, he and Amy were present in the 13th century. (TV: The Big Bang) Amy seemed to also remember those events, and displayed a fondness for the Auton Rory both during her honeymoon (TV: A Christmas Carol) and during a kind of lullaby to her newborn child Melody Pond.
